Dust obscuring most of the Liaoning region of China and parts of northern and western Korea. Left: March 23, 2002, a relatively clear day. Right: April 8, 2002, a day of extremely dusty skies. Storms transport mineral dust from the deserts of China and Mongolia over great distances, as well as pollution from agriculture, industry and power generation. Asian dust has been detected as far away as Colorado. Thick clouds of dust block substantial amounts of incoming sunlight, which in turn can...

The Aral Sea, located in Kazakhstan and Uzbekistan in central Asia. Left: 2000. Middle: 2004. Right: 2009. Once one of the largest inland bodies of salty reservoirs in the world and the second largest sea in Asia, the Aral Sea has shrunk dramatically over the last 30 years. One of the main reasons why is crop irrigation: water has been drawn off by upstream feeder streams. As the sea diminishes, noticeable changes in climate conditions and increasing sandstorms are affecting the area. Images...

Carbon dioxide levels in our atmosphere are rising. Left: July 2003. Right: July 2007. Both images show the spreading of carbon dioxide around the globe as it follows large-scale patterns of circulation in the atmosphere. The color codes in these two pictures are different in order to account for the carbon dioxide increase from 2003 to 2007. If the color bar for 2003 were to be used for 2007, the resulting 2007 map would be saturated with reddish colors, and the fine structure of the...

Cloud swirls forming patterns around the 1050-meter-high 0.65-mile-high summit on the island of Socorro, Mexico. Left: April 23, 2000. Right: May 9, 2000. These turbulent atmospheric eddies form in the wake of an obstacle, while the surrounding clouds make the vortex patterns visible. To the northeast, much subtler disturbances are associated with the tiny Isla San Benedicto. Both islands are part of a group known as the Revillagigedo Archipelago, and are located about 400 kilometers 250 miles...
